From what we hear from friends, who live on/near golf courses, in N. California, the coyotes have taken control of some courses night and day. They are becoming very aggressive in a little over a month.
A friend who, lives down an arroyo from a golf course had a deer killed by a critter in her back yard. Her yard guy is now carrying bear spray (don’t believe that a bear killed the deer).
We are on the San Francisco peninsula. House cat remains have been found in neighborhoods for years around here. Most people think it is coyotes. I haven’t run across any in our neighborhood, but I do see them when hiking in the hills. A couple years ago I passed one when hiking in the huge pasture at Westwind Barn in Los Altos Hills. He was going opposite me and we passed maybe 75 feet apart, both eyeing the other warily. Gave me the creeps.
I’ve seen them swimming across rivers in Skaggs Island, Sonoma County.
